Password Generator is a free online tool that creates strong, random passwords and passphrases directly in your browser. Every password is generated locally using the Web Crypto API, so the values you create stay in your browser and are never sent to or stored on our servers.
Use it to create unique passwords for online accounts, a long WiFi password for your router, or a memorable random-word passphrase for a master password. Not sure if an existing password is safe? Run it through the password strength checker to estimate its crack time.
Why Password Generator?
- Client-Side Generation: Password and passphrase generation happens entirely in your browser.
- Cryptographically Secure: Randomness comes from the browser's Web Crypto API, not a predictable algorithm.
- Free & No Signup: No account needed, no limits, no paywalls.
- Fast & Lightweight: Built for speed with minimal page weight.
- Mobile Friendly: Works perfectly on any device.
